The Fairchild MIL-STD-1553 Serial Multiplex Bus Tester

The Fairchild Serial Multiplex Bus Tester (SMBT) is a general purpose computer controlled MIL-STD-1553 stimulus/response/analyzer. SMBT has been selected to fulfill the data bus testing requirements of the Air Force Modular Automatic Test Equipment (MATE) systems. The design is three separate devices or functions: a monitor, a bus controller, and a remote terminal simulator, which may be operated in any combination. The purpose is to integrate the Monitor, Controller, and Remote Terminal functions into a single unit. SMBT may be controlled and synchronized by a master computer performing a coordinated total checkout of a unit under test. The monitor allows a collection of 1024 word 'windows' of bus traffic and simultaneously accumulate error statistics in all bus traffic. A system self check is incorporated as an additional feature of the design. In summary, the SMBT is designed to provide necessary stimulus, response and analysis capability for MIL-STD-1553 Line Replaceable Unit (LRU) testing.
